HHG9 USB3.0 Dual Monitor HDMI KVM Switch for 2 PCs: This dual monitor KVM switch allows you to control them with a keyboard, mouse, and a single or dual monitor setup. The display function requires each laptop/PC to support two or more screens. KVM Switch Dual Monitor Ultra HD 4K@60Hz: The dual monitor HDMI KVM supports a maximum resolution of 4K@60Hz (3840 x 2160) YUV 4:4:4. Compatible with 3840x2160 @ 30Hz, 1080P, 1080P 3D, 1080I, 720P, 576P, 576I, 480P, and 480I. Supports separate audio and microphone output. Supports Emulated EDID: This KVM dual monitor switch emulates the monitor's EDID and saves the monitor's resolution and refresh rate. Each input port comes with an EDID emulator, so the PC always has the correct display information. With two computers using two monitors, even when switching to another machine and back, everything will be displayed where it should be on the screen. Without EDID, windows may move when switching. You no longer have to wait for the windows to adjust. 3 USB 3.0 Ports, Audio and Microphone Output: The KVM switcher for 2 monitor PCs has three integrated USB 3.0 ports that recognize keyboards, mice, printers, scanners, and other USB devices. Supports ultra-fast USB 3.0 data transfer up to 5Gbps and is backward compatible with USB 2.0/1.1 devices. The upgraded design hides the cables at the back and leaves the USB 3.0 port on the front for connecting USB sticks. It also supports independent audio output and microphone output. Two Switching Modes and Wide Compatibility: You can switch computers by pressing the button on the panel or using the wired remote control (included in the package). LEDs indicate the active computer. It also supports HDMI devices without USB signal input, such as DVRs and NVRs.
